Vadonka!

I set the values from the first post for UV and for setCPU profiles. Is it still recommended or are there any different values? What do you think which one is better SetCPU or Antutu CPU Master?

Köszönjük a sok munkád!:)
[LG Optimus 2x] vadonka:
the older setcpu working perfect, the latest antutu cpu master also, so its equal. use whatever you want :) (im on antutu cpu master currently, have all profile what the setcpu have) if you used the setcpu just make sure that dont upgrade from the market.

Szívesen :)
[LG Optimus 2x] upetro:
I understand that, but it is not the voltage or frequency that is causing the no-boot issue. I know that becouse i was running all your previous OC kernels with no issues. The problems started with the 23.April OC version. I can still run the the 18.April OC version, even undervolted, but cant even boot the 26.April OC version with higher voltage(your test kernel). So it has to be some sort of fs problem/corruption.
[LG Optimus 2x] Shadowchaz:
I installed the latest oc version on a fresh install of cm7 Kang 93 and it froze on the LG logo. The keypad lights remained on. Had to run back to ext 3 to fix system partition as it was corrupted. This is the first time one of your kernals would not load for me. :-(
[LG Optimus 2x] vadonka:
the one big update after the 18th of april is that the kernel version 3.0.28->3.0.29

but i dont think this caused the problem
[LG Optimus 2x] upetro:
It just might be, since the 3.0.28 OC kernel works fine for me.
[LG Optimus 2x] ergoen:
I really appreciate what you're doing for our phone vadonka!

I'm having the boot-problems aswell though, and here's the weird thing:

-1st lg logo goes away quickly

-get stuck for like 20 seconds on 2nd lg logo, then it continues

-cyanogenmod7-logo starts spinning, spins for a while, then stops!

do I have the same error as other people or is this my own fault for having some weird apps installed?

edit: this is with the (currently) latest OC kernel. (18th of april OC kernel works just fine, nothing since then)
[LG Optimus 2x] elvnox:
YES!

This one:

boot fine ;)
[LG Optimus 2x] vadonka:
i forgot that note about this

im change using the ext4 driver for the ext2/3 too after the 18th version, so i revert back this. the 17h version have the ext2/3 driver too and the ext4 separated.

maybe that was the problem, hmmm.
[LG Optimus 2x] MisjudgedTwat:
i can't imagine how the fs stuff should be the problem when the "stock" version works fine. i see it like... what is the exact difference between "stock" and "oc"? the issue must be there for my logic.

i hoped that i can give you anything to read, so i pulled some logcat files while i tried to boot, and there is never ever any error message which tells anything. just some app related warnings and stuff like that.

and every logcat file stops at random positions, that also explains the different stucks.

the interesting thing: when i have my usb cable on it, to get the logcats the boot process seems to be more successfull... it keeps longer without freezing. now i also had the pin screen for 2 times. (maybe the phone tells me that way... "now i finally have enuff power to give all the requested voltage to the cpu" ? just an idea)

i hope my english is understandable :D

EDIT:

i forgot to say: the 17h build doesnt change anything for me.

Mine got stuck for 3 minutes on LG Bluish logo with 1204261736-ETaNa_OC_DS_OTF-3.0.y build. Then I I removed the battery and reinstalled 1204181217. It lasted a while for booting but everything went like before after installing 120426 kernel.

Last ROM: moon101 MIUI 2.3.2

Same here with 1204261736-ETaNa_OC_DS_OTF-3.0.y build.Phone has problem booting.Back to 18th of april.I was thinking...Which is the difference between 18th of april and the other?Can you make kernels adding only one option each time?This will help finding the problem i think.Is there a way for noobs to trace - debug the procedure of booting so we can spot the problem?

2.6.32.y weird problem randomly sdcdard not mounting

Hi there,

I got Temasek's CM7 ROM with his kernel, everything was working very fine for a while. Then I decided to install the 2.6.32y LOC Lite kernel, and now my phone randomly doesn't mount the SDcard after booting. Then a reboot is needed, and sometimes another, before it mounts the SDcard.

After booting, when I see the screen to enter the PIN, in the top left corner "preparing sdcard" is shown for two to three short times right after eachother. I know it's normal that this is displayed, but I don't know if it's normal that it appears for two to three short times.

I flashed back Temasek's kernel, but the issue remains....

You guys any idea? Thanks.
[LG Optimus 2x] @dap:
12.04.23 OC initially booted for me but was unstable, with random reboots. 12.04.18 OC booted fine and am running 12.04.25 OC now...
[LG Optimus 2x] tonyp:
Then it's not kernel related. Backup, error check and reformat your SD card.
[LG Optimus 2x] dmxl:
Well, It's either kernel/rom/phone related. I noticed I can't connect the phone to my pc anymore as a mass storage device. A yellow exclamation point appears in device manager, next to USB composite device. When I put the sdcard in another Android phone, device manager doesn't give any errors, and all is working fine, I can transfer files... Weird stuff..
[LG Optimus 2x] temasek:
Reflash kang without any custom kernel and try out your usb mass storage.
[LG Optimus 2x] dmxl:
Yeah... done... didn't solve the problem....going to make a nandroid backup now, and try a stock rom..

---------- Post added at 03:09 AM ---------- Previous post was at 02:35 AM ----------

Ok... I think it's a hardware problem in the phone. Gosh.... Stock ROM gave a bootloop for some reason, so I first reflashed a clean version of your modified CM7 rom, didn't solve things, then the original CM7 ROM, didn't solve things either.

Besides the problems with the usb cable/pc link, the phone keeps having problems mounting the sdcard every now and then... I'm baked... think I'm gonna have to send the phone back? I just got it..
[LG Optimus 2x] tonyp:
Before sending it in you should try a nvflash.

Before thatvuninstall the USB drivers, reboot and reinstall them, then plug the phone to another USB port. Try it without inserting the sdcard, does it work for the internal SD?
[LG Optimus 2x] buedi:
Still the boot issue with latest "2012.04.26H14" OC kernel :-/!

Thx for your hard work!
[LG Optimus 2x] Shadowchaz:
For some reason my USB mass storage has never worked on a pc but works fine on a Mac. If you have access to a Mac try it :)
[LG Optimus 2x] buedi:
Now I tried to flash the 18th version from april! Getting the message:

- kernel file not found

- ramhack is disabled by default

- building the new kernel...

ERROR: Packing kernel failed!

This problem exist right after flashing 18th version after the 26th OC version (stock has the same install problem for me)!

Yeah, big business ;-)!

--> Recovered with cwm (made a backup before) - I think I wait for a few more releases! So back to version 18th April :-)!

[LG Optimus 2x] lucfig:
@vadonka, will u add the snappy compression and a non OC version of kernel 2.6.32.y or the last one is final?

Thanks in advance
[LG Optimus 2x] vadonka:
if the main linux kernel will be updated, i will update too, and maybe add this extra features too, but currently im working on the 3.0.y

the latest release is fast and provide very good battery life (as good as the 2.6.32)

so im focus with this and trying to eliminate the bugs.
[LG Optimus 2x] powwow88:
120426 oc stuck at 2nd lg logo for me too. I'm using cm7 temasek kang 94.

I tested those test versions. I wiped cache and dalvik before each. I always waited a few minutes at 2nd lg logo.

Results:

18th_apr_orig_recompiled - booted up

test1 - booted up

test2 - stucked at 2nd lg logo

test3 - stucked at 2nd lg logo

test4 - stucked at 2nd lg logo
[LG Optimus 2x] vadonka:
thx!

the good thing the test2 have only this modification:

bd68ff219756155b6ea97cc5901e7216b981d691 Enable slqb by default

1f213e51013c9f17b0605687fed63b56c4b593bc Add updated slqb allocator

i wait for a few other confirm that the test2 the first what cant boot.
[LG Optimus 2x] upetro:
I just tested all of them. I confirm that the test2, test3 and test4 dont boot.

18April and test1 work.I also noticed that the working versions are not 3.0.29 but are 3.0.28.
[LG Optimus 2x] vadonka:
yeah i know, here is the commits regarding to the test numbers:

test1:

because the test2 the first what cant boot it clearly see that the SLQB allocator cause the issue, at least i hope :)
[LG Optimus 2x] upetro:
So is it possible to build a kernel without the SLQB allocator commit, and add all the other commits?

I will test it as soon as you build it.
[LG Optimus 2x] vadonka:
Uploaded a new version. Its have all of the latest patch's just removed the SQLB allocator.
[LG Optimus 2x] vadonka:
already done ;)

It works. Vadonka, you are the best! Seriously!
[LG Optimus 2x] ergoen:
Thanks alot, this one works for me aswell!

[LG Optimus 2x] Schmeichel1:
Works for me too ... :)
[LG Optimus 2x] MisjudgedTwat:
and now the weirdest thing... all test builds and even the 120426 versions are running fine for me today! i just don't get it.
[LG Optimus 2x] vadonka:
welcome to the developers world :D
[LG Optimus 2x] MisjudgedTwat:
man, this drives me crazy. i hate it when something is not logic :D

but guess what... yesterday my battery was always between 50% and 20% while i flashed. today between 100% - 50%. you said yesterday that everything is stable for you... was your battery also above 50%? - just a thought.

i will now let the battery go down to 30% again and then i will test again.

latest build of today is also running nice btw.

and thanks for all the work man! (i think i didnt mention that yet)
[LG Optimus 2x] tomislav177:
Vadonka.

You are the king of LG Optimus 2X world. :)

Everything is wotking now.

Thx.
[LG Optimus 2x] moludo:
nice work vadonka!

with today´s update everytinhgs works fine .No more lg logo freeze. Thankx
[LG Optimus 2x] yukkio:
someone who does not work?

BR.
[LG Optimus 2x] Sörnäinen:
*lol*

The latest build works for me, too. And it FLIES. i usually think it's just a psychological effect when new builds seem to be snappier ... but in this case I really think it is.

The screen seems more responsive, and apps like instagram start up fast and connect speedy.

Does any of that make sense? ;)
[LG Optimus 2x] hadi_rena:
Hmmm even the caused have been found here my test result :D

original recompiled = Success

test #1 = Success

test #2 = Freeze at bootanimation

test #3 = Stuck at 2nd LG logo

test #4 = Stuck at 2nd LG logo

27 April = Success
[LG Optimus 2x] vadonka:
probably the test2 stuck at the 2nd logo if you reboot again, but no matter now :)
[LG Optimus 2x] Feiervogel:
same problem here, are there any solutions?
[LG Optimus 2x] Lapiduss:
Finally 3.0 working!!!!!!!!!! Thanks Vadonka and all who have tested kernels!

I've installed kang 94, kernel 1204271054-ETaNa_OC_DS_OTF-3.0.y.zip, re-initialized system partition and all work! No problem with mounting system..
[LG Optimus 2x] vadonka:
the few latest version reinitialize the system partition automatically if needed.

thx for morcx.
[LG Optimus 2x] morckx:
At least the messages: "this will take a minute", "DO NOT INTERRUPT!"

and "saving system content" should appear immediately. If they don't, possibly the "mount" command to list the mounted fs takes forever (or less likely mounting of /system or /sdcard). In any case you probably need to re-format at least your system partition using the script here http://xdaforums.com/showpost.php?p=24709087&postcount=2894 and re-install.

Is there anything special about your installation? What CWM version do you use? And could you post your /tmp/recovery.log ("cat /tmp/recovery.log" via adb shell in cwm-recovery) and the output of "ps" during the hang?

If everything works, the re-init process should take less than 2 minutes. And since the the kernel version of yesterday (appr. 1:30pm) progress information during save and restore should be printed.
[LG Optimus 2x] bekaman:
Hi Vadonka,

Is it ok to run V6 supercharger script on your latest kernel? ?

Thanks before

try this: http://www.donka.hu/android/kernel/LGE-KaNG_kernel_only_120113.zip

if its ok, i will compile the other versions too at morning
[LG Optimus 2x] Ferrum Master:
LOL. As an electronics engineer and a authorized service technician for certain manufacturers, I haven't read such bull**** in a while. STOP amusing people here.

There indeed are few revisions of the board... god, even Nokia 6230 had 8 of them...

How in the world LCD is connected with a spectrum analyzer?

Cheap radio IC? It does a really different job for example like old a SEMC RAY module? Do you know what pain is to get FCC certificate and what does it mean? Should I remind you why the phone is one third cheaper that SGS2? Have you ever ordered and build a PCB multi layer with components on both sides? How the costs sum up?

The most fun part.. lift the NAND IC... We'll see how the phone will act afterwards, such as half baked Samsung refurbished board... not even calibrated if you are lucky enough...

The power ic part made my cry, I wont even comment it...

The only thing that differs in between users and why we are getting different battery time results is network coverage - that is IT. Otherwise your phone is FAULTY.

Why UV is unstable? Gosh eureka, because the logic VDD level gets too low and RAM controller goes haywire... for some it works because there are lucky samples, just like every manufacturer cherry pick their cpus and make Black or Extreme editions, there is no magic... plain math and statistics... just as Intel i7 memory voltage can not exceed 1.65V as it can fry the uncore part of the cpu...

And... If you are calling yourself an educated engineer... why didn't you simply open up a Level 3/4 P990 STAR datasheet... and then search those unknown parts?

To sum UP... The only difference we have is OC/UV potential, other power elements on the board are replaceable and within nvidia recommendations and numbers change due different manufacturers ie Philips or TI and does not influence overall stability of the phone, as it has gone through calibration routines. There is one exception guys... those are refurbished units... it is kind of a lottery with them... you never know what...
[LG Optimus 2x] vadonka:
well disassemble one of these phone and see for yourself what is here :)

its more simplier what you think. the pcb only have a few layers, not much.

by the way i disassembled an sgs2 too already. its almost cheap like the lg board. the sgs2 is just a big overhyped overpriced candy phone.

two 256mb memory ic with smd pin. it can be replaced. i do this with my motorola milestone phone not a long ago. replaced the 256mb memory ic with an 512mb and worked. its sad that i found pictures from some disassembled o2x and not like mine. so even the board is different! in my phone only the cpu covered with black plastic, the other part not, however in this page almost every ic covered, but the description is remain intact. it not just talking about remanufactured compoment.. lame the lg for that manufacturing such a cheap hardware, but at least not so expensive like the sgs2...

the power ic is not an ic, its a block of component, there is a description on the top layer of the pcb, even the manufacturer marked it.

the spectrum analyzer what i have is more like a multimeter not just for the audio, have a lumx/brightness sensor too. its simply analyze the brightness level not more.

about the voltages, TI, NI, or any other manufacturer making different ic.

it not just about the voltage, many other thing can be influenced with the oc problems. i have already too much problems with the "not existed" difference between the manufacturers. two ic from same type and model and the one is working the other is not in the same enviroment. even the TI using component from second hand.

the network coverage causing the different battery life? seriusly? do you even check what is eating the battery the most? its not the radio. if the phone in the standby mode the radio is still active, however the battery drain is very very slow. do you even think of that?

the top battery eater is the lcd screen, the second is the cpu and the gpu.

if the mobile network is not active the cell standby battery consumption is almost nothing. of course if the 2g/3g is active its eating the battery for sure.

Level 3/4 P990 STAR datasheet: there is no such thing in public what you say, never heard of it even in the nvidia forum

its hard to believe that the LG publish the whole phone datasheet to the public just like that.. but if you have a copy i will see :)

if you are talking about the service manual its just useless. the lg is not that famous that open the secret book and show the magic :)

To sum: you come here, if im so amusing why dont you just leave? you trying appeart to smart without see what is in the phone. write a totally offtopic post with not a nice tone and finally you are referenced such a datasheet what isn't even exist.

what we have talking about?
[LG Optimus 2x] vadonka:
but remain in the theme of the topic:

disabling the zcache seems to be solved the boot problem in some devices.

i leave enabled the memory compaction, it will gain a little extra free memory (10-20mb). the total memory is not increased but the used is a bit lower.

the cleancache is related to the zcache without that is almost do nothing, so i disable it too.

im using currently this settings:

normal:

cpu1 on when freq is above 655mhz for at least 200msec

cpu1 off when freq is below 503mhz for at least 1500msec

freq's:

216mhz - 790mV

503mhz - 800mV

816mhz - 850mV

1015mhz - 950mV

1100mhz - 1000mV

1216mhz - 1100mV

1408mhz - 1200mV

1504mhz - 1300mv

powersave:

cpu1 on when freq is above 655mhz for at least 300msec

cpu1 off when freq is below 816mhz for at least 1000msec

freq's:

216mhz - 790mV

503mhz - 800mV

655mhz - 820mV

816mhz - 850mV

1015mhz - 950mV

1100mhz - 1000mV

1216mhz - 1100mV

1408mhz - 1200mV

I updated my kernel to 120112 (Powersave base version) and had some problems, so I flashed back to 120109 powersave coreboost. Paired with CM7 nightly 204, I couldn't be happier. Thanks to you and other developers, keep it up!

thinking of installing the power save kernel to have better battery life than my current 8-10hrs on temasek's CM kernel

just wondering what is the difference between base and shared? i'm guessing the shared one is for ramhacking? i'd like to have the least problems as possible so i guess i should use the base version?
[LG Optimus 2x] Trystan34:
WOW!! After testing the power save version I love it. The battery lasts a lot longer!!

Thank you Vadonka
[LG Optimus 2x] CVonV:
i've just installed the base power version and 480p youtube videos don't work in browser.. but 360p and 720p do.. 480p (HQ) in the youtube app works though

what were u getting before under what kind of usage? did you use shared or base?

i've set my max cpu frequency to 1408MHz from the default 1015MHz to improve responsiveness. hopefully it doesn't lessen the battery life drastically
[LG Optimus 2x] joe1660:
Just installed your new kernel normal shared and I have problem with the camera in video mode. It's always stacking
[LG Optimus 2x] Trystan34:
Does the power save version (shared memory version) include Voodoo Sound?
[LG Optimus 2x] vadonka:
the shared version is a little buggy, i will not build shared version in the next update.

in the korean developer forum this patch is reverted for now. use the basic or the traditional ramhack version instead of the shared.
[LG Optimus 2x] vadonka:
every version have the voodoo sound.
[LG Optimus 2x] joe1660:
I installed the normal kernel with the RAMhack and the video is ok again. In your first shared version I didn't have problem with the video. When I installed the last share version I had the problem

---------- Post added at 01:46 PM ---------- Previous post was at 01:36 PM ----------

i will ask you something little stupid. i have font installer but it has only little fonts that supports greek. i like very much the "playful" fonts from the stock build. i saw that when i install every kernel of you, the fonts are back to the defaults. so can you make one kernel that will contain the playful fonts? or just a script to install from recovery the playful fonts
[LG Optimus 2x] vadonka:
if the carveout size is not lowered but the kernel cmdline edited for allocate more memory to the system the phone will not boot. if somehow booting many app will not work, for example: started a game but right after that is closing and dropped to the home screen.

the shared memory patch is a workaround for this, it can be allow that using a minimal overlapped memory without the phone have common problems. but it seems to not perfect...

the idea is originally from the 4pda.ru forum, but even there is reverted.
[LG Optimus 2x] vadonka:
updated

i hope this version will working for everyone..
[LG Optimus 2x] ron_gangte:
Please build the shared memory version. I use it. :-\

Thank You! :-)
[LG Optimus 2x] vadonka:
you dont have issues with it?
[LG Optimus 2x] 4lph4:
Hi vadonka, it would be a problem for you to prepare also a package for the 64MB ram hack?

With that version the video 1080p is not working but 720p is more than enough for me. I feel is a good compromise with the added memory available.
